Get response from PHP file using AJAX -

so here's issue, using ajax (jquery) post form process.php page needs echo out response such apple or plum. i'm not sure how take response process.php , have stored variable...

here's code have far:

<script type="text/javascript"> function returnwasset(){ alert('return sent'); $.ajax({ type: "post", url: "process.php", data: somedata; success function(){ //echo server sent back... } }); } </script>

also need echo response in process.php in json? or plain text fine?

sorry if sounds stupid question, first time doing such in ajax.

ps: how name post request in above code?

<?php echo 'apple'; ?> pretty much literally need on server.

as js side, output of server-side script passed parameter success handler function, you'd have

success: function(data) { alert(data); // apple }

php ajax
